An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In FIG. 1, 1 is the lower shell, 2 is the upper shell, 3 and 4 are joint flanges provided on the lower shell 1 and the upper shell 2, respectively, and 5 is on the opposite side of the joint surface of the flange 3.4. 6 is an O-ring provided on the joint surface of the 7 flange 3.4, 7 and 8 are a clamp with an upper claw and a clamp with a lower claw that clamp and tighten the flanges 3 and 4, respectively. A plurality of protrusions 9 are provided that match the tightening grooves 5 of the flanges 3 and 4, and a plurality of protrusions 9 are arranged at regular intervals around the flanges 3 and 4, and each is connected and supported by a support rod 10 so as to be openable and closable. There is. 11 is a wedge-shaped groove provided on the outside of each claw clamp 7.8, and 12 is a wedge ring with a wedge-shaped cross section facing the wedge-shaped groove 111, which is divided into two on the outer periphery of the flange 3.4. , both ends of which are connected by jack bolts 13.

In the configuration described above, the tightening of the flange 3.4 is performed by the fourth
As shown in the figure, each claw clamp 7°8 is arranged on the outer periphery of each flange 3, 4 by aligning the protrusion 9 with the tightening groove 51,
By aligning the wedge ring 12 with the wedge-shaped groove 11 of each claw clamp 7.8 and turning the jack bolt 13, the wedge ring 12 is fitted into the wedge-shaped groove 11.
The flange 3.4 is simultaneously tightened over its entire circumference by respective claw clamps 7.8 as shown in FIG.
